| 2023-11-15 | VFS: Add stat | Anton Kling | |
| 2023-11-15 | VFS: Bug fix. Uninitalized structure member. | Anton Kling | |
| This was found thanks to kmalloc now filling new allocations with random data. | |||
| 2023-11-15 | ext2: Bug fix. Add padding to the block group descriptor. | Anton Kling | |
| 2023-11-13 | AHCI: Add write function. | Anton Kling | |
| This also changes the ext2 filesystem so it will now write to the file it mounted. Currently the file mounted is /dev/sda which points to a SATA drive. | |||
| 2023-11-13 | Kernel: Add support for AHCI and make use of it with the current filesystem. | Anton Kling | |
| It will now also create a corresponding /dev/sd* device for each detected SATA drive. The filesystem still writes using the ATA driver. This should be fixed soon. | |||
| 2023-11-13 | Memory: Fix problem where certain tables did not get marked as kernel. | Anton Kling | |
| This caused the tables to be cloned instead of having the pointer copied on the new page directory creations. This is just a solution to the symptom of having a bad design for memory managment. Maybe I will figure out something better. | |||
| 2023-11-13 | Kernel: Remove kmalloc_eternal | Anton Kling | |
| I would like to be able to free some of those objects but I have not decided upon how that will be done yet. Even if not freeded the added complexity of having two functions does not make the extra bytes saved worth it IMO. | |||
| 2023-11-13 | Crypto: Implement fast insecure RNG for overwritting memory areas. | Anton Kling | |
| This is mainly done to test for uninitlalized memory and find bugs faster. Therefore it does not need to be cryptographically secure or perfectly uniform. Xoshiro256++ seems like a good fit. | |||
| 2023-11-13 | Kernel: Add typedefs.h | Anton Kling | |
| 2023-11-13 | ARP: Save the IP, MAC of incoming ARP requests | Anton Kling | |
| 2023-11-13 | Exceptions: Output CR2 on page fault | Anton Kling | |
| 2023-11-12 | AHCI: Add very basic AHCI and some additional helper functions to mmu.c | Anton Kling | |
| Currently certain parts of the code are taken from osdev wiki as there seems to be very little documentation that I can find on how H2D FIS is structured. Those parts, especially some of the uglier parts of the example code will be rewritten/changed. | |||
| 2023-11-12 | Kernel/PCI: Add functions for getting BAR and specific PCI devices by | Anton Kling | |
| class | |||
| 2023-11-10 | Ext2: Change char* to u8* where the type is referencing data and not a C | Anton Kling | |
| string | |||
| 2023-11-10 | Kernel Style: Change uint*_t -> u* | Anton Kling | |
| 2023-11-10 | Kernel/Memory: Fill new allocations with random data. | Anton Kling | |
| This should make it easier to spot uninitalized memory being used. | |||
| 2023-11-10 | Syscall: Cleanup code and remove dumb usage of get_vfs_fd. | Anton Kling | |
| 2023-11-10 | Kernel: Remove old dead code | Anton Kling | |
| 2023-11-10 | Kernel/fs: Dynamically allocate based upon file size. | Anton Kling | |
| This commit also changes "unsigned char" to "char". A slight step in the direction of making my coding style less bipolar. | |||
| 2023-11-09 | Kernel/fs: Dynamically allocate depending upon file size of directory. | Anton Kling | |
| This also solves a bug where the data_p pointer could get out of range due to incorrect assumptions being made about the ext2 directory layout. To be fair even a faulty ext2 directory layout should not be able to cause memory bugs. | |||
| 2023-11-09 | Kernel: Remove old comment | Anton Kling | |
| 2023-11-09 | Kernel: Initalize the file descriptor pointers in the proess struct to | Anton Kling | |
| zero. | |||
| 2023-11-08 | Kerenl/MMU: Remove dumb bug as a result of uninitalized memory | Anton Kling | |
| The kernel would randomly crash. Turns out I did not zero out the frames so my page allocator seemed to get into some weird state. | |||
| 2023-11-08 | Kernel/MMU: Detect system memory and dynamically adjust memory usage available | Anton Kling | |
| Previously this would be hardcoded but now it can be detected by the bootloader and passed in via the multiboot header. | |||
| 2023-11-08 | Kernel/MMU: Detect system memory and dynamically adjust memory usage available | Anton Kling | |
| Previously this would be hardcoded but now it can be detected by the bootloader and passed in via the multiboot header. | |||
| 2023-11-08 | Kernel/MMU: Create a seperate table for heap allocation | Anton Kling | |
| 2023-11-01 | Kernel: Add a simple TCP implementation | Anton Kling | |
| 2023-10-31 | Kernel: Remove all O0 optimizations on functions. | Anton Kling | |
| The kernel can now fully compile under O3 without any noticable problems :) | |||
| 2023-10-31 | Kernel: Bug fix, infinite loop when checking string memory permissions | Anton Kling | |
| If the string is pointed to a very exact location in memory the loop never finishes. | |||
| 2023-10-31 | Meta: Create simple build scripts for kernel, userland and general enviroment | Anton Kling | |
| 2023-10-31 | Meta: Move kernel and userland to their own folders. | Anton Kling | |
| This is to allow both the kernel and the userland to share certain header files and to make the folder structure a bit more clear. | |||
